That sounds great.
It's tough to do, and the information isn't complete.
Not only is it incomplete, trainer styles and data can be very trainer-specific. There's a horse today in the 11th race @ Gulfstream, #5, who's training data speed has changed dramatically (significantly slower), but the horse is in fact thriving, and the major factor is actually trainer change.
Some barns publish consistent data and run a bunch of horses predictably.
The Kentucky Derby and Triple Crown coverage alos offers a window for a glimpse of how top horses are prepared for racing. (walks, gallops, gate-schooling, works, etc...)
DRF Formulator is a must have. Ability to play around with statistics such as layoffs between races.
I think it's a great idea, interested in how it moves forward and your presentation of the fitness.
